Step-by-step, no fluff.
Practical guides for improving athletic performance and training smarter with measurable data.
Countermovement Rebound Jump Test: Full CMRJ Testing Protocol
A CMJ that lands and rebounds into a second jump. Get the CMRJ protocol, contact-time benchmarks, and why it catches fatigue a jump-height test misses.
How to Measure Cricket Bat Swing Velocity with a Sensor
Bat speed alone hides swing-plane errors. Learn the IMU protocol for straight drive vs pull shot swing plane, angle benchmarks, and 2 cited studies.
Double Poling Power Test: Pole Impulse and Left-Right Asymmetry Protocol for Cross-Country Skiers
Roller-ski coaches track watts and split times but rarely test the individual pole. A field protocol to measure per-pole impulse and left-right asymmetry.
Curve Sprint Test for Soccer: Protocol, Radius, and Deficit
A great 20m sprint time can still lose the arcing run to the byline. Get the penalty-arc curve sprint protocol, radius options, and deficit scoring.
Curve-Sprint Timing: Standardizing Radius and Entry Angle
Left curve 0.18s faster than right, every single week? A fixed-radius, fixed-entry-angle curve sprint protocol that stops your cones from lying to you.
Cycling Repeated-Sprint Fatigue Test: Protocol, Power-Decay Scoring, and Norms
One max sprint won't tell you who survives lap nine of a crit. A 10x6s cycling protocol that scores power decay across repeated efforts, with real cutoffs.
Fixing Deadlift Velocity Shifts From Grip Style: Standardizing Hook, Mixed and Strap Pulls
Switch from straps to hook grip and initial pull velocity jumps 15%? That is grip mechanics, not new strength. Here is how to standardize the reading.
Dragon Boat Paddle Power Stroke Test: Tethered Catch-to-Drive Protocol and Left-Right Pairing
A tethered dragon boat paddle power test scores catch-to-drive force, not stroke averages, so left-right paddlers get paired by real numbers.
Equestrian Rider Core Stability: An IMU Test for Pelvis and Trunk Sway Against Horse Movement
Equestrian rider core stability test: measure pelvis-to-horse coupling and trunk sway with dual IMUs. Protocol, skill-tier norms, and 2 cited studies.
Estimated 1RM Keeps Changing Daily: Is It Noise or Real Readiness Drift?
Your velocity 1RM swings 8kg between sessions with nothing changed. Separate measurement noise from real readiness drift and build a stable baseline.
Field Hockey Drag-Flick Power Test: Measuring Rotational Power and Leg Asymmetry
A big medicine-ball throw score doesn't fix a flick that clips the crossbar. Get the drag-flick-specific power test protocol, reference values, and setup.
Field Hockey Injection Speed Test: Measuring the Penalty Corner Push-In for Timing
A flicker testing at 24 m/s still misses corners when the push-in arrives late or hot. Get the injection speed protocol, real research, and reference points.
